Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00099 | $0.01544 |
| Opus 5.5 | $0.00040 | $0.00618 |
| Sonnet 5.5 | $0.00020 | $0.00309 |
| Haiku 4.5 | $0.00010 | $0.00154 |
Grade A, and why
update-stack scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
The source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

update-stack is a skill published in the GitHub repository pierreb-devkit/Node (20 stars, last pushed today), with no licence file. It adds 99 tokens to every session and 1,544 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

push-to-forked-pr
Push the current working tree directly to a GitHub PR whose head lives on a fork, without creating a new branch and without pushing to origin (which is usually the upstream). Invoke when the user says things like "push straight to PR.
version-release
Choose and apply the correct semantic version bump for this repository. Use for every user-visible release, before merge when a change set should ship as patch, minor, or major, and whenever package/plugin/desktop version metadata must stay synchronized.
history-portability
Import Claude Code or Codex history and move complete CCAM datasets between machines. Use when rescanning provider history, importing a copied directory, uploading JSONL or archives, exporting a backup, restoring it idempotently, or verifying that tokens, workflows, runs, rules, and pricing survived.
release-guard
Run release-readiness checks for this repository. Use when validating docs, scripts, verification coverage, and operational safety before merge or release.
pull-request
Use this whenever the user asks to "open a PR", "ship this", "create the pull request", "make a PR", or once a Vue feature/fix is verified and ready to push. Full lifecycle: branch → commit (commitizen) → issue → draft PR → CI → ready → autonomous monitor loop (fix comments, resolve threads, iterate until CI green +…
update-stack
Use this whenever a downstream Vue project needs to absorb upstream Devkit Vue changes — triggers on "update stack", "sync with devkit", "merge upstream", "pull stack updates", "resolve stack conflicts". Two-phase: ISO merge (stack modules stay byte-identical to upstream) then project alignment (apply MIGRATIONS.md…
